Title: Improvements in or relating to roller bearings
IPC: F16C19/28
Filed: 1932-12-28
Abstract: 395,604. Roller bearings. AKTIEBOLAGET SVENSKA KULLAGERFABRIKEN, 17, Artillerigatan, Gothenburg, Sweden. Dec. 28, 1932, No. 36712. Convention date, Jan. 7. [Class 12 (i).] In a roller bearing having two or more sets of cylindrical rollers, inner and outer cylindrical race members, and guide rings for the rollers, at least one guide ring is axially fixed to one of the race members, at least two guide rings are axially fixed to the other race member and none, or not more than one, of the axially fixed guide rings is made integral with a race member. In Fig. 1, two sets of cylindrical rollers 3, 4 are positioned between a ring 7 fixed to the inner race member 2 and rings 5, 6 axially fixed with respect to the outer race member 1. The ring 7 is split and engages a groove 14 extending most of the way round the member 2, the raised interrupted part taking into a recess 17 adjacent the split 16 to prevent relative rotational movement between the parts 2, 7. The rings 5, 6 which are undivided, are non-rotatably connected to the member 1 by tongues engaging corresponding recesses in the member 1, and are axially fixed by split rings 8, 9 which can be sprung into grooves 13 by means of holding lugs adjacent the splits. In assembling the bearing, the ring 7 is positioned first, then the roller set 3, the ring 5 and the ring 8. The bearing is then reversed and the roller set 4 inserted similarly. In a modification, undivided rings are positioned on either side of the ring 7. In another form, four roller sets are spaced by five guide rings, the two outer rings and the centre ring being axially fixed on the outer and inner race members respectively and the remaining rings being axially movable. One of the outer rings is integral with the outer race member. The thrust, according to its direction is taken by one of two double roller sets. Another modification has also four roller sets spaced by five guide rings, three being axially fixed to the outer member 1, and two to the inner member 2. A form with three roller sets has four axially fixed guide rings on each of the members 1, 2, these being between and outside the roller sets. Undivided rings may be positioned on each side of an inner split ring in any of the constructions. The undivided rings may all be made the same size and their tongues may be dispensed with. All the constructions are designed to take axial thrust in both directions.

Abstract: 931,216. Waveguide filters. STANDARD TELEPHONES & CABLES Ltd. Oct. 19, 1961, No. 37579/61. Class 40 (8). Spurious modes of operation are prevented in a multi-cavity band-pass waveguide filter by providing aperiodic attenuation means in the coupling sections between the cavities. The filter may comprise cavities of lengths l, l1 bounded by inductive posts 2, 3 ; 4, 5 and spaced apart by a coupling section having a length equal to an odd number of quarter wavelengths. One or more attenuating cards or adjustable lossy magnetic plugs 7, 8, 9 arranged in the coupling section are dimensioned to provide an attenuation within the pass band of between 0.1 and 1.0 dB. These are effective to suppress spurious pass-bands arising from parasitic resonances. The filter may be of the type having cavities of different loaded Q-factors giving a Chebychev or Butterworth transmission characteristic. To this end, the lengths l, l<SP>1</SP> &c. differ by different amounts from one half-wavelength at the centre frequency of the pass band.

Abstract: 523,322. Electrolytic deposition of copper. REVERE COPPER & BRASS, Inc. Dec. 30, 1938, Nos. 37906, 37907 and 37908. Convention dates, Dec. 30, 1937, Nov. 12, 1938, and Nov. 12, 1938. [Class 41] In coating stainless steel surfaces, particularly the exterior surfaces of the bottoms of cooking vessels, with copper, the surface is first prepared to receive the coating, a thin coating is applied by using an electrolyte of low copper concentration and a low density plating current and a thick coating by an acid bath of high copper concentration and a highdensity plating current. A final coating of nickel, chromium or other corrosion-resistant metal may be applied. The preparatory treatment may be with an acid to generate hydrogen at the surface or the surface may be made a cathode or alternately an anode and a cathode in a sulphuric acid bath which may contain also sodium sulphate and chloride. The treatment is effected by supporting the vessel V by resilient prongs' 69 attached to the shaft of an electric motor 35 so that its base is immersed in an electrolyte in a bath 1 and is surrounded by a perforated lead electrode 11. The vessel is rotated during the electrolysis, and current is supplied through connections 25, 45 so that the vessel forms first the anode and then the cathode, a resistance being switched into the circuit to cut down the current when the vessel forms the cathode. To form the thin coating of copper, the vessel without being dried is treated in a bath of acid copper sulphate at about 80‹ F. or a copper cyanide bath at 110-130‹ F. An apparatus similar to that used for the preparatory treatment is made use of, the lead electrode being replaced by the flat copper electrode, and provision being made to discharge air below the centre of the vessel to agitate the electrolyte : or to pump the electrolyte against the electrodes. The thick coating of copper is applied in a similar apparatus using a stronger acid copper sulphate bath which may also contain aluminium sulphate and current densities up to 500 amps. per square foot and temperatures up to 150‹ F. To obtain even deposition, a shield consisting of a steel plate covered with indiarubber and having a central opening may be interposed between the electrode and the base of the vessel.

Abstract: 1500247 Electrical terminal insertion apparatus; shearing; punching AMP Inc 14 Sept 1976 [1 Oct 1975] 38005/76 Headings B3A and B3W Apparatus for inserting an electrical terminal 25<SP>1</SP> into a cavity 20 in a terminal support 18 comprises a ram 74 movable towards the terminal support, means for locating the terminal in the path of travel of the ram so that the terminal is entrained by the ram and thereby inserted into the cavity, and a control member 80 movable ahead of the ram, the arrangement being such that the movement of the ram is terminated when the ram has moved a predetermined distance after the control member 80 has engaged the terminal support 18. The control member 80 may be a tube which is attached to a portion 73 of the ram 74 by a spring 78. A portion 74a of the ram 74 is located within the tube 80 and is provided with a stud 124 which projects into a slot (122) Fig. 5 (not shown) in the wall of the tube. The terminals (25) are fed to a station 90 attached to a carrier strip (36), Fig. 2 (not shown). At the station 90 a punch 60 descends to sever the leading terminal from the strip and push it through an opening 100 into the tube 80. The ram 74 is now advanced and drives the tube 80 by way of the spring 78 towards the support 18 until the face 96 of the tube engages the edge 34 of the cavity 20. The ram 74 continues to advance pushing the terminal down the tube 80 and into the cavity 20, the spring 78 becoming compressed. The movement of the ram is terminated when a shoulder 84 thereon engages the end 82 of the tube 80. A blade 76 moves with the ram 74 to trim the wire 16 prior to the wire being received in the slots (30), Fig. 2 (not shown) of the terminal. The terminal strip 23, Fig. 8, is fed to the station 90 by a finger 66 which engages in holes (24) in the carrier strip (36), Fig. 2 (not shown), the finger 66 being attached to an arm 46 connected to a lever 62 pivotable about a pin 63. Retraction of the punch 60 causes a cam to drive a shaft 56 to the right against the action of a spring 64 to operate the lever 62 and thus advance the strip 23. The position of the pin 63 within a slot is adjustable by a screw (7), Fig. 1 (not shown) to adjust the travel of the finger 66. When the terminals (25) are to be inserted into a plurality of cavities 20 in the housing 18 of a stator 12, the stator is positioned on an arbor 50, Fig. 9, with the latter arranged vertically. The arbor is then pivoted about an axis 53 to the horizontal position shown and a hand wheel 54 rotated to align a cavity 20 with the ram 74. A recess (108), Fig. 11 (not shown) in collar 116 on the arbor receives the tip of a spring loaded indexing plunger (110) when the said alignment is achieved. When no terminal is to be inserted into one of the cavities 20, a screw (118) in the appropriate recess (108) is set to prevent the plunger (110) engaging in that cavity.
